Qasr mosaic leopard and VMS Leo/August image

[Koen G]

I stand corrected, Sam and JKP are right: it could actually be a tree if the cat's tail ends behind its back and there is an invisible horizon running behind it. I also agree that the Qasr mosaic provides the best example for this tree. 

Interestingly, the same set of mosaics show a different tree behind the lion. The one with the three branches usually appears behind the leopard.
